Why do we only have the dashcam videos? I want to see the LIDAR data. Also, Uber definitively has ways to render all the sensor data into a video which shows the objects which was detected (or lack of detection).
I suspect the CPU in this satellite is a BAE Systems RAD6000, commonly used in NASA spacecrafts. It’s extremely expensive and also brittle due to the materials used. Very hard to get due to export regulations. I tried to source one of these CPU’s outside US once.
First you base64 encode the file so you can print it. Then to enable multiple recipients you can fax it. But I prefer to put the paper file into a glass bottle and throw it in the ocean.
You can't cut it. But the Carbide is brittle and with enough pressure it can shatter Carbide ring manufacturers have this in mind and intentionally make "weak points" on the ring so it can be removed in an emergency.
It's not cheap. I contacted almost all suppliers worldwide, and in EU the price is roughly 2000-3000 EUR for a single sphere. However, one supplier in China called Sintec had in stock for a mere USD 375. It's a grade 50 sphere with a precision of a few thousands of a millimetres:)
Funny to see this article here now. For the last few weeks I've been geeking out on exotic materials, and especially Tungsten Carbide. I even went so far to buy a polished Cobalt binded TC 70mm sphere from China. It's virtually indestructible and very few materials such as diamond can scratch it.
Whenever I need to remember something, I switch my phone wallpaper/lock screen to one of the default ones which I normally don't use. Then I can usually associate what I needed to remember. Works better than writing a note, or adding a reminder/alarm since these notifications is easily missed/ignored.
I think this uses one of the available GIF extensions (e.g plain-text, custom data, or other) since gif is a block based binary file. Animation blocks in one part of the file, then for the other blocks you could just put random data (which is ignored by the GIF parser) until you find the MD5 collision.
This is why I only listen to music in PCM 24-bit WAV's instead of compressed audio. The difference is huge due to the missing frequencies in MP3 and similar formats.
Decoding performance is roughly 13 microseconds on a relatively slow 2013 MBA. Other features which will be added is websocket streams, encoder and further performance optimizations.
well, it's not surprising web apps are slow. as an example, 1dash1.com mentioned above: 57.480 lines of JS across 8 separate domains. and the result? site is loading slow (at least on my 500MBit/s fiber connection) and the browser is executing a lot of stuff, most of which is not really efficient or time sensitive (or required). this is how most sites does it, it has to be better ways.
I don't claim this to be fast, as it isn't really optimized for performance at all. I created this mainly as a learning experience using ECMAScript 6, as well as multiple processes in node/io. The plan is to add more options later, or perhaps another interesting way could be to see how fast this thing can be.
Instance cost for Rackspace is basically nothing depending on data transfer, they have a relatively new program they call Developer+[0] which is basically 50USD for free per month. The VPN server software is open-source, I use OpenSWAN (couldn't get the new fork Libreswan up an running correctly).
Running my own L2TP/IPSec server for that as well. Older versions of iOS consistently closes the VPN connection when the phone was locked (or not connected via USB). iOS 8 is more stable it seems, because it keeps the VPN connection active for longer.
I'm living in Shanghai. Still connected fine over a IPSec tunnel. I run my own VPN server on Rackspace/AWS (only 2 public IPs), the connection is and has been relatively stable (about a year). 12MBit/s from Shanghai to the IPSec server in Hong Kong, 38ms consistent ping (100MBit/s connection). Using a Cisco SMB router, so the connection is pure IPSec and standard ports.
